AP Statistics Curriculum COURSE DESCRIPTION

The purpose of AP Statistics is to introduce students to the major concepts and tools for collecting, analyzing and

drawing conclusions from data. Students are exposed to four broad conceptual themes:

1. Exploring Data: Describing patterns and departures from patterns

2. Sampling and Experimentations: Planning and conducting a study

3. Anticipating Patterns: Exploring random phenomena using probability and simulation

4. Statistical Inference: Estimating population parameters and testing hypotheses

According to College Board, upon entering this course students are expected to have mathematical maturity and

quantitative reasoning ability. Mathematical maturity could be defined as a complete working knowledge of the

graphical and algebraic concepts through mathematical analysis, including linear, quadratic, exponential and

logarithmic functions. As such, successful completion of Algebra II is a pre-requisite for enrollment.

The College Board also expects that students will learn how to leverage technology in order to explore and analyze data.

As such, all students will also have access to a Ti-84 to enhance the analysis of data during classroom instruction, at

home practice, and on the AP Exam. The calculator will be utilized on a daily basis throughout the course, as well as

being supplemented with instruction on utilizing Google Sheets, Microsoft Excel, and other online apps to further

enhance the analysis of data and create statistical displays.
